1
00:00:00,300 --> 00:00:06,930
Now it's time to talk about the nun when actually the nun is how far from its name?

2
00:00:06,960 --> 00:00:08,310
Yeah, it is none.

3
00:00:08,460 --> 00:00:09,000
Nothing.

4
00:00:09,220 --> 00:00:14,220
OK, so if I type this the equal nun.

5
00:00:16,070 --> 00:00:18,020
And if I break this.

6
00:00:20,570 --> 00:00:27,170
Actually, this this is not the same as this, the white space, the white space has value, but this

7
00:00:27,170 --> 00:00:28,360
one, which means none.

8
00:00:28,850 --> 00:00:29,990
It is not set yet.

9
00:00:30,290 --> 00:00:33,200
It is it doesn't have any very arbitrary value.

10
00:00:33,230 --> 00:00:36,170
OK, so this is not like that.

11
00:00:36,170 --> 00:00:38,400
Zero, not like the white space.

12
00:00:38,430 --> 00:00:40,960
No, this is something different, which means that this is none.

13
00:00:41,300 --> 00:00:47,600
So if you can see that this is known as you can see not zero, not white space, nothing, which means

14
00:00:47,600 --> 00:00:52,010
it is the value for this variable is arbitrary or it is not set yet.

15
00:00:52,340 --> 00:00:53,910
So let's check this out.

16
00:00:53,930 --> 00:00:57,630
Actually, you can see that the value is not OK.

17
00:00:58,100 --> 00:00:58,860
Thanks for watching.
